Question

Quizplus · Accepted Answer

A statistical power between .80 to .95 is generally considered acceptable for most research studies. This means that there is a high probability of correctly rejecting the null hypothesis when it is false, indicating a significant difference or relationship between the variables being studied. A power below .80 may indicate that the sample size is too small or the study design is not optimal. Choosing a power above .95 may lead to overpowered studies, which can produce statistically significant results even when the effect size is small or trivial.
